PIANO-FORTE ACTION.

SPECIFICATION forming part of Letters Patent No. 397,239, dated February5, 1889.

Application filed October 16, 1888. Serial No. 288,266. (No modeld Toall 2071 0712 it may concern:

Be it known that we, HELLMUTH KRANICH and JACQUES EACH, of New York, inthe county and State of New York, have invented a certain new and usefulImprovement in Piano-Forte Actions, of which the following is aspecification.

The ohject of this improvemcn t is to pro I duce a simple, light,inexpensive, and withal effective means for to the lever. this purposeemhodying our improvement, and then point out the novel features in theclaims.

In the accompanying drawings, Figure 1 is securing a damper-head a sideview of a damper-lever embodying our l improvement. Fig. 2 is a backview of the same. Fig. is aback view showing a dampen head adjusteddownwardly upon the damperlever. Fig. i is a hack view showing thedamper-head as oscillated or twisted relatively to the damper-lever outof line with the damper-lever. Fl 5 is a back view showing thedamper-head as turned or rotated around the damper-lever. Fig. (i is atrans verse section taken at the plane of the dotted line .20 to, Fig.1.

Similar letters of reference designate corresponding parts in all thefigures.

A designates the damper-lever. It may he madein any desired manner. Itis here shown as consisting of a wooden portion, a, and. a wire portion,o extending therefrom.

B designates the damper-head. of any desired form; but it is here shownas longitudinally on the hack and transversely grooved on the front, soas to he divided into bifurcate portions 1) b t'ront.

L designates a clip, here shown as consisting of a strip of metal havingrounded ends,

but which will normally be separated a slight distance. The cylindricportion is adapted to D, extends through the end portions of the clip,through the block of the damper-head *0 will describe a means for It mayhe I opposite thegroove therein, and engages with a nut which is tittedin said groove. The nut tits so snuglyin thegroovetha t it is unahle toturn therein. Ohviously a nut otherwise arranged or a suitahlescrew-thread ,)tliei'\\'ise provided in the head of the damper wouldserve the same purpose of engaging the screw. \Ve have shown a washer,E, ot' felt oranalogous material,arranged hct ween the clip and theblock ot the dz'unper-head. This means for connecting the damper-head.with the damperlever is exceedingly simple, and although it may heoperated very readily and easily it is remarkahly cheap. it affordsprovision for numerous adjustnn' nts, which we have illustrated. 13yloosening the screw, so that the clip will relax its grip upon the wireof the damper lever, the clip, and with it the damper-head, may he slidlengthwise ot' the wire, either upwardly or downwardly. \Yhen adjustedto the desired posititm, the screw may he inserted lartherinto thedamper-head or its nut to tighten the grip of the clip upon the wire ofthe damper-lever, and also to cause the clip to bear with more forceagainst the damper-head or the washer intermediate of it and thedamper-head. This adjustmentmay he easily understood hy comparingFig. 2with Fig. 3.

It may he desirable in some cases to oscillate the damper-head on anaxis coinciding 5 with the center of the screw, as illustrated in Fig.i. This may he done by simply with drawin the screw slightly to relaxthe pressure of the'clip against the damper-head. consisting of a blockof wood, Z), convexed Then the damper-head may he oscillated, andsuhsetpiently it may he seeurtwl hy inserting the screw again. These hit'urcate portions are shown as having felt [1 1)" on the Anotherpossihle adjustment is illustrated in Fig. This :nljustment consists inturning or rotating the head hodily around the wire ot thetlampmr-lever. To etlect this adjust ment, the screw is withdrawnsut'ticiently to allow the clip to relax its grip upon the wire of thedamper-lever. When the clip relaxes its hold, the head may he rotated.Afterward the screw may he farther inserted to tighten the clip againand secure the head. fit the wire (1 ot' the damper-lever. A screw,

lYhat we claim as our invention, and desire toseeure by Letters Patent,is

1. The combination, with a damper-lever and damper-head, of a clipsecured to the damper-head and adapted to be adjusted lengthwise of thedamper-lever, substantially as specified.

2. lhe combination, with a damper-lever and damper-head,of a clipconsisting of a strip of metal bent between the ends in a cylindricalform and havingthe ends lapped, substantially as specified.

The combination, with a damper-lever and damper-head, of a clipconsisting, of a strip of metal bent between the ends in a cylindricalform and having the ends lapped, and a screw passing-through the lapped.ends and entiin'ing' the head, substantially as specified.

4. The eombinatimi, with a damper-lever and damper-head, ot' a screwpassing through an extension from the damper-lever into the damper-head,and constructed to permit the oscillation of the head relatively to thedamper-lever upon the axial line of said screw, substantially asspecified.

5. A damper-lever having a cylindrical portion or wire, a clip having acylindrical portion fitting the cylindrical portion of the lever, adamper-head, and a screw for tightening the clip upon the damper-lever,all being so combined that the clip and the damperhead may be rotatedaround the damper-hr Yer, substantially as specified.
